So I'll be 18 weeks tomorrow and I'm kind of disappointed that I don't really have a bump yet. I'm on the heavier side to begin with, but I figured I'd see a little something. A friend of mine is a few weeks behind me and she definitely has that distinct little bump. I've had to buy maternity clothes because my pants don't fit comfortably anymore. At my last check up, (16 weeks) I found out that I'm down roughly 12 lbs since the beginning of my pregnancy. I've had severe nausea but I haven't been vomiting from morning sickness.
